Title: Device for warming up and maintaining the temperature of the contents of a feeding bottle or the like
IPC: A47J36/24
Filed: 1962-09-20
Abstract: 990.693. Electrically heated feeding bottles. M. VAN DEN BOSCH. Sept. 20, 1962 [Sept. 21, 1961; Jan. 25, 1962], No. 35844/62. Heading H5H. A device for warming a feeding bottle includes a heating jacket, in the form of an arcuate sheet, for placing around and elastically gripping the bottle, and a holder for accommodating the bottle during warming-up of the bottle contents, the holder having a thermostatic switch which reduces the heating current when the bottle is at the desired temperature, whereafter the temperature of the jacket and bottle is maintained substantially constant during use, by means of the loss of heat from the jacket to the surrounding air, irrespective of the removal of the bottle from the holder, and of the amount of the bottle contents. The heating jacket 1, Fig. 5, may consist of a conductive layer sandwiched between two layers of insulator (Fig. 3, not shown); a heating wire embedded in insulating material separating the two walls of the jacket (Fig. 2, not shown) ; or a linear heating element 13, Fig. 4, attached to a single sheet 12 of material of high thermal conductivity. For warming-up, the bottle is placed on the holder 14, on a surface to the underside of which a thermostat is attached. At the desired temperature, the thermostat contacts open, whereafter the heating current is reduced by its diversion through an indicator lamp 19, and the current through a further resistance mounted adjacent the thermostat and in parallel with either the supply transformer 18 or the lamp 19 is increased, such that its heating effect retains the thermostat contacts open upon the subsequent removal of the bottle from the holder, for use; a cold bottle subsequently placed upon the holder produces a sufficiently rapid withdrawal of heat to close the contacts again. In modified arrangements, operation of the thermostat switch reduces the voltage tapped from the supply transformer; and the heating current is retained at its lower valve upon removal of the bottle by a switch in series with the thermostat and operated by the pressure of the bottle (Fig. 7, not shown).

Title: Improvements in or relating to circuit arrangements for electric relays
IPC: H03K3/57
Filed: 1967-08-11
Abstract: 1,142,400. Transistor relay operating circuits; telephone exchanges. SIEMENS A.G. 11 Aug., 1967 [12 Aug., 1966], No. 36984/67. Headings H3T and H4K. A circuit for energizing the operate or release winding RKA of a relay via a path including a contact 1KA of the relay which is initially made, comprises a capacitor C1 which is charged via a rectifier G11 when a voltage U is applied to the circuit and an electronic switch T1 which, when the voltage is removed or reduced, is rendered conductive by the voltage across the rectifier and discharges the capacitor through the relay winding. Thus, in the circuit shown, when U is removed, the capacitor begins to discharge through the emitter-base path of transistor T1 making the collector-emitter path conducting. C1 thus discharges through the relay coil to operate or release the relay independently of its contacts 1KA, 2KA. The arrangement is said to be suitable for party line connections using latching relays, or in the conversion of three wire circuits to two-wire. A single release coil may serve for a number of relays.

Title: Stabilized silicon grease composition
IPC: B01J19/06
Filed: 1961-10-17
Abstract: A treated silica, for use in a silicone grease composition (see Division C3), is prepared by merely mixing a finely divided silica (fume, xerogel or aerogel) with boric acid, trimethoxyboroxine (methylmetaborate) or a trialkylborate in which the alkyl radicals contain from 1 to 5 C atoms.  Preferably the mixture is heated at 100 DEG  to 250 DEG  C. for 1 to 6 hours.  The boron compound is preferably used in amount to provide from 0.001 to 1 pt. (by wt.) of B per 5 to 17 pts. of silicon.  In Example (3) (H) 10 pts. of silica aerogel were mixed with 0.75 pt. of trimethoxyboroxine (0.135 pt. B) and the resulting mixture was heated at 200 DEG  C. for 5 hours.ALSO:A stabilized grease composition comprises (1) a major amount of a silicone oil, (2) a minor amount of a finely divided silica as thickener, and (3) a stabilizing amount of boric acid, trimethoxyboroxine (methylmetaborate) or a trialkyl borate in which the alkyl radicals contain from 1 to 5 C atoms.  The greases are made either by blending the various ingredients together, or by pre-treating the silica with the boron compound (see Division C1) and blending the resulting product with the siloxane.  The mechanical stability of the grease is further improved by heating the grease at 100 DEG  to 250 DEG  C. for 1 to 6 hours.  The siloxanes used may contain alkyl, alkenyl, aryl or halo-hydrocarbon radicals.  The silicas (fume, exerogel or aerogel) are used in amount (by weight), e.g. of from 5 to 17 parts per 100 parts of siloxane.  The boron compounds are preferably used in amount to provide from 0.001 to 1 pt. of B per 100 pts. of siloxane.  If desired, some of the silica may be replaced by silica which has been treated with octamethylcyclotetrasiloxane, as described in Specification 806,563. Other fillers and stabilizers such as pentaerythritol and high molecular weight polyalkylene glycols and glycol ethers, may also be added.  Examples are given.
